Mini Satellite Attitude Determination and Control System
HOW Does IT FUNCTION?
Controlled by a patented magnetic field design, a spherical motor is capable of spinning in X, Y, and Z axes. Moreover, bias-currents are applied to each phase of the motor, this enables the motor to combine 3-axis magnetorquers into this device as well.
Application: Attitude Control
Every satellite in orbit requires precise orientation control along the X, Y, and Z axes. This is the so-called attitude control, which is essential for optical sensing satellites and broad-band communication satellites. To achieve this, we use a tactical grade gyroscope and fine sun sensor as the attitude determination sub-system; the spherical motor functions as the attitude actuator.

There are two obstacles for commercial players to enter the space industry: Rocket Launching Cost and Satellite Building Costs. While Satellite minimization is the key to tackle the second issue, Attitude control devices, among all sub-systems, are among those devices that cannot be shrunk due to physical limitations. Tensor Tech developed a groundbreaking spherical motor technology by replacing three motors with only one. Our device’s weight, size, and power consumption are reduced by 2/3 compared with traditional systems. Our invention also might enable the space industry for wider commercial applications by allowing a satellite mission with lower costs and capabilities of carrying more payloads.
